Redirection

>  content override the file content, If file is already having the content
>> Will append the content to the existing content in the file

In Both case, if the file is not present it will create a file and write the content to the file

By default echo command prints the output to screen. But if we redirection arrows it can store to files

How to unzip to different directory

Using -d parameter we can extract the zip package to different folder
-q –> silent mode

Lets extract to /tmp folder

Curl command to retrieve the Rest api response (JSON)

Most of the time curl command is used for calling the rest api

In simple term, Rest api is URL(https://example.com), when we call that url , you will get a response data.

The most of the case the response data will be a JSON

Actual Data in GUI : https://github.com/vigneshsweekaran/hello-world/releases/tag/clean
